[0021] In some embodiments, the air branch pipeline 101 extends into the silicone oil tank 3 and extends horizontally. A plurality of exhaust holes are provided on the air branch pipeline inside the silicone oil tank 3 to accelerate the combination of silicone oil and air.

[0022] Working principle:

[0023] As Figure 1 described, air enters the first air branch pipe 101 through the first air pipe and extends to the bottom of the silicone oil tank 3. Bubbles are formed at the bottom of the silicone oil tank 3 through the exhaust holes provided on the first air branch pipe 101, and the entire silicone oil tank 3 is filled with silicone oil gas. A rotameter 5 is installed on the first air branch pipe 101 to adjust the amount of gas entering the bottom of the silicone oil tank 3. The intake air volume is controlled at 40m 3 / h. The silicone oil gas is transported to the burner through the first silicone oil gas pipe 301 and the second silicone oil gas pipe 302. To prevent the condensation of silicone oil gas in the pipeline, an electric tracing band 4 is added to the second silicone oil gas pipe 302. The temperature of the electric tracing band 4 is adjusted to 95°C through the temperature control panel 7. The silicone oil in the silicone oil tank 3 is transported through the silicone oil filling tank 2 and the silicone oil filling pipe 201, and a regulating valve 6 is provided on the silicone oil filling pipe 201 to adjust the amount of silicone oil;

[0024] As Figure 1 described, the fan 8 transports air to the second air pipe 9, and the second air pipe 9 transports air to the second air branch pipe 902. The second air branch pipe 902 is connected to the second silicone oil gas pipe 302 and leads into the hose 12. The hose 12 uses a hose 12 with high temperature resistance, high pressure resistance, and corrosion resistance to avoid damage and leakage. The silicone oil gas mixed with air is led into the combustion chamber 10 through the hose 12. A combustion-supporting pipe 901 is also provided on the second air pipe 9, and a large amount of combustion-supporting air is transported to the combustion chamber 10 by the fan 8. The second air branch pipe 902 and the combustion-supporting pipe 901 are both provided with regulating valves 6 to adjust the gas flow switch. A natural gas pipe 11 is also provided in the combustion chamber 10. Natural gas enters the combustion chamber 10 through the natural gas pipe 11, and a combustion reaction occurs inside the combustion chamber 10 under the action of natural gas. The fine particles of the atomized silicone oil vapor enter the process system to capture acid mist particles, so as to reduce acid mist emissions and meet the tail gas emission standards;

[0025] As Figure 1 shown, in the volatilization system, compressed air is introduced into the silicone oil tank 3 to cause the silicone oil to generate bubbles and volatilize in the container. The volatilization temperature of the silicone oil is 35°C. The temperature of the device can be maintained by the electric heating plate 701. If the ambient temperature is higher than 35°C, the temperature can be controlled by adjusting the electric heating plate 701;

[0026] As Figure 1As shown, when the entire system stops running, the air remaining in the pipeline is likely to damage the device. Therefore, an anti-blow pipeline 102 is provided at one end of the air pipeline, and an anti-blow pipeline 103 is provided at one end of the air branch pipeline 101. When the system stops, air is continuously conveyed in the anti-blow pipeline 102 and the anti-blow pipeline 103, and the remaining silicone oil gas in the system is all passed through the combustion chamber 10 into the process gas pipeline 13 to prevent the remaining silicone oil gas from corroding the device;
